​The Copenhagen Perinatal Cohort (CPC) is a population-based birth cohort of 9125 individuals born at the National University Hospital between September 1959 and December 1961. One physician (Dr Aage Willumsen) was responsible for collecting information on the mothers social, general medical, and obstetrical history during pregnancy. He interviewed all mothers 5 days after births, and 67% of the mothers at their first visit to antenatal clinic. The mothers and their children were examined at birth and invited to follow-up examinations of the children at 1, 3 and 6 years of age, which were done at the hospital. At the age of 41–43 years study participants were sent a questionnaire on lifestyle risk factors and health issues.

The cohort participant, their mothers and fathers have been prospectively followed up via linkages with national registers on vital statistics, health and socioeconomic circumstances and other cohort studies.
